Having writing on top of photo in Gallery and being able to click on it and write an explanation of project

[Jades1]

I’m currently using the “Cohub” Theme (GitHub - StaticMania/hugo-cohub 1). In the exampleSite (GitHub - StaticMania/hugo-cohub 1), there are four photos in a gallery, and I’m wondering how I would create a gallery for projects vs photos, so it would be great to be able to write over photos I choose and then have those expand and be able to explain the projects in greater depth. I’ve looked through the config.toml file and the .yml file where the images are stored as well as the blog layout further down (which does have a click feature where it takes you to another page). How could this be created?

Thanks!
